Platinum on Carbon Catalyst
for PEM fuel cells and water electrolysis
Hydrogen Fuel Cell Catalysts
Momentum Materials® provides hydrogen fuel cell catalysts that facilitate the electrochemical reactions of oxygen and hydrogen to generate electricity for transportation and stationary power applications. Our catalysts deliver high performance and outstanding durability, making them ideal for both mobility and stationary use.
HER and PEM electrolysis catalysts
We are also developing electrocatalysts for the hydrogen evolution reaction (HER) in PEM electrolysis, aiming to reduce platinum loading while maintaining strong performance and long-term stability.
Platinum on NCP Supports™
By depositing Pt on NCP Supports™ — our proprietary nanoporous carbon support featuring three-dimensionally interconnected nanostructures and exceptional carbon corrosion resistance—we create Pt/NCP catalysts that deliver high performance across various conditions and achieve 2.5 times the durability of benchmark catalysts.

Frequently Asked Questions
What is the price of a Pt/NCP catalyst?
Pricing is dominated by the platinum cost. In most Pt/C catalysts, platinum accounts for 65–90% of the total cost. Higher Pt loading means more platinum per gram and therefore a higher price. Although NCP Supports™ are more expensive than conventional carbon black, in Pt/NCP Catalysts platinum still represents 65–80% of the total cost. For small quantities, you can find pricing for our 50% Pt/NCP in our online shop. For large quantities, pricing benefits strongly from economies of scale. Contact us to discuss your required quantity and supply timeframe for more accurate pricing.
What catalyst types are currently available for purchase, and in what batch sizes?
Our standard catalyst is 50% platinum on NCP-10-HT or MCP-4-HT. Our production batch size is 100 grams, with a monthly production capacity of 3 kg. We also offer customized variations, with platinum loadings ranging from 20% to 50% and carbon supports with different pore sizes to meet specific application requirements.
Can I purchase the nanoporous carbon support only, without any catalyst loaded?
Yes. We offer NCP Supports™ in a range of pore sizes and grades. Please see our NCP Supports™ and MCP options to learn more.
What makes your platinum catalysts different from others on the market?
Our catalysts are made with our proprietary nanoporous carbon, featuring precisely tuned pore sizes and interconnected pore networks that enable high catalyst utilization and facilitate mass transport. Platinum-loaded NCP Supports™ have demonstrated outstanding carbon durability, offering long-term economic benefits and a lower total cost of ownership. In addition, check out this article comparing multiple carbon supports: Mesoporous Carbon Cost for Hydrogen Fuel Cells.
Can you support large-scale production orders?
Yes. While we are proud to support R&D projects with small-batch orders, our facility is fully equipped to scale production to meet the demands of commercial manufacturing, making us a reliable partner for your growth.
What kind of technical support do you offer?
Our relationship with clients goes beyond the sale. We provide comprehensive technical support, from initial consultation and catalyst selection to integration assistance, to ensure you get the maximum performance from our products.
